What is the difference between Claims based authentication vs What is provided by OAuth.

I am looking for conceptual difference and not technical difference. When do I choose Claims over OAuth and vice versa.

Claims based authentication is proposed by Microsoft and build on top of WS-Security. But OAuth is more a open source protocol that is being proposed to allow fetching resources from different portals based on a security token.

Claims also has this concept of token (SAML encoded or X509 certificates).

I am trying to understand when do I choose Claims over OAuth and vice versa.

Thanks
